Fujitsu has developed revolutionary new read head and media technologies that will enable hard disk drive recording densities of up to 300 gigabits per square inch. The new technologies are expected to lead to the commercial introduction within two to four years of 2.5" hard disk drives with capacities up to six times the recording density available today.

"Fujitsu is proud to once again offer a technology breakthrough that will lead to better and faster products for tomorrow's consumers," said Mike Chenery, vice president, advanced product engineering at Fujitsu Computer Products of America, Inc. Fujitsu's latest technology advancements feature a new Current-Perpendicular-to-Plane (CPP) mode Giant Magneto-Resistive (GMR) head that achieves more than three times the playback output levels of current HDDs by allowing current to flow perpendicular to the GMR element. Existing GMR read heads, which operate in the Current-in-Plane mode, are considered to have a limit of approximately 100Gb/in² in density due to their small signal output level. Fujitsu's new CPP GMR head also boasts improved sensitivity to data signals. Higher sensitivity when element size becomes smaller results in increased recording density. Source: Fujitsu
